Public concern over impacts of chemicals in plant and animal production on health and the environment has led to increased demand for organic produce, which is usually promoted and often perceived as containing fewer contaminants, more nutrients, and being positive for the environment.
These benefits are difficult to quantify, and potential environmental impacts on such benefits have not been widely studied. This book addresses these key points, examining factors such as the role of certain nutrients in prevention and promotion of chronic disease, potential health benefits of bioactive compounds in plants, the prevalence of food-borne pesticides and pathogens and how both local and global environmental factors may affect any differences between organic and conventionally produced food.
"It is an interesting and timely snapshot of our understanding of these issues with well-written articles from respected authors in many areas relevant to human health ranging from the effect of n-3 fatty acids to dietary flavonoids to selenium to contaminants in foods. Although the book is necessarily limited by the set-up of the original workshop, the choice of authors and the breadth of topics explored are excellent."--Experimental Agriculture
